[0044] The heater 31 includes an electromagnetic heating coil; a wire fastener is provided on one side of the fixed arm 32; the lead end of the electromagnetic heating coil is connected to the wire fastener; and the heater 31 is electrically connected to a temperature control device. The temperature control device can control the heating conditions. For example, the heating process includes two stages.

In the second stage, when the colloid reaches 120-130℃ (the typical curing temperature of the colloid is 90-170℃), the bracket and colloid enter a constant temperature stage. Heating continues when the temperature is below this level and stops when it is above it. After holding at this temperature for 40-50 seconds, the colloid is completely cured. This allows the 1510 colloid to cure quickly without carbonization, maintaining both high production efficiency and ensuring the bonding quality of the accessories.
